| 摘 要： | 采用铝造渣球和新型Al-Ca质改质剂,在某钢厂180 t转炉出钢时,对转炉出钢带入钢包的下渣进行了改质处理试验.针对铝镇静钢与沸腾钢两种出钢方式,分别研究了两种改质剂对转炉渣改质的影响及对钢液的作用.试验结果表明:每炉加入200 kg Al-Ca质改质剂的效果与加入400 kg铝造渣球的改质效果相当;应用两种改质剂均未见有明显增碳;在达到同样改质效果时,应用Al-Ca质改质剂既便于精炼处理,又具有非常明显的成本优势.

| Abstract: | An Al-Ca-based conditioning flux was newly developed and the comparative experiments were carried out between the conventional Al-CaO-based and the Al-Cabased conditioning fluxes to control the tapping slag in ladle for the 180 t BOF at a certain steel plant.Then,the effects of the two conditioning fluxes on the slag and both the Al-killed and unkilled molten steel were investigated.The results indicated that 200 kg of the Al-Ca-based conditioning flux is equivalent to 400 kg of the Al-CaO-based conditionin... |
